Hello

For my thesis i need to design a fixture for a milling operation. To design it, i need to have the cutting force for the milling machine to optimize all the geometric parameters. The spec given to me
are:

Milling condition:END MILLING
spindle speed- 3000 rpm
feed- 500 mm/min
depth of cut- 2 mm
width of cut - 6 mm


TOOL:
Cutter dai- 10 mm
cutter - Solid carbide
4 flute
nose radius- 0.5 mm


MMR= d.o.c *w.o.c * feed
MMR found to be 6000 mm3/min

hi, you can use this formula N=1000xVc/3.14xd

hi
Thank you for your reply. I have calculated using the following procedure
Step 1 : calculate MMR
Step 2 : Calculate spindle hp= MMR* Unit power Attachment 255942
unit power can be assumed from the attachment
Step 3: Calculating the torque (in lb)= (Spindle hp*63030)/RPM
Step 4: Using torque equation T=(Force* D.o.c)/2
can calculate force...
is this procedure is feasible?

that is right , i am sorry but i thought you haave asked about cutting speed because me i didnt seen adjust the sentence

nice day man.......

@albasha79 hahaha thts ok no prob...
thank you bro...
